Here’s what some happy people had to say:

“There was WAY more content than I expected, so I felt like it was a really good deal!” ~Sandy P.

“Marisa is an expert in her field of sports nutrition and it comes through in her hydration class. All athletes need to watch Perfect Hydration to enhance their performance and learn so much valuable information beyond just hydration. Marisa teaching style makes it easy to learn by providing excellent graphics and breaking down the science to make it easily understood.” ~Katharine J.

“The message was clear, well-organized, and to the point. I love how the videos were short. I love how you emphasized sodium instead of potassium for cramps–that really stuck with me!” ~Valeria M.

“This 9-module course is a must-have for competitive and recreational athletes alike. Sports dietitian and triathlete Marisa Michael takes you from basic hydration physiology and troubleshooting to choosing a hydration product that’s right for you. The course wraps up with practical tools to formulate your own personal hydration plan, which can be applied to any sport or activity. I highly recommend this hydration course.” ~Niki S.

“Marisa does a fantastic job translating complex scientific information into digestible information all athletes can use and apply to their own training plans. The information in this course is applicable for novice exercisers to elite athletes and everyone in between. Unlike other courses, Marisa provides you with the tools to directly apply the nutritional science to your unique needs by teaching you how to calculate your sweat rate, create a personalized hydration plan, and explore the world of hydration supplements and their impact on sport performance.” ~Hannah F.
